How get selected text from FEDIT window ?
I mean somthing like as WM_GETTEXT, but only selected text(not all text)

I think using WM_COPY, but its sometimes not handful solution.

See how it is implemented in fasmw's source:

Code:

  select_all:
        mov     [fepos.selectionLine],1
        mov     [fepos.selectionPosition],1
        mov     [fepos.caretLine],-1
        mov     [fepos.caretPosition],1
        invoke  SendMessage,ebx,FEM_SETPOS,fepos,0
        invoke  SendMessage,ebx,FEM_GETPOS,fepos,0
        invoke  SendMessage,ebx,FEM_GETLINELENGTH,[fepos.caretLine],0
        inc     eax
        mov     [fepos.caretPosition],eax
        invoke  SendMessage,ebx,FEM_SETPOS,fepos,0
        jmp     finish

This is right ?

Code:

invoke  SendMessage,[FEDITHwnd],WM_SETTEXT,0,MyTxtBuffer  
invoke  SendMessage,[FEDITHwnd],FEM_ISUNMODIFIED,0,0
invoke  SendMessage,[FEDITHwnd],FEM_SETMODE,0,0
invoke  SendMessage,[FEDITHwnd],EM_EMPTYUNDOBUFFER,0,0

Tomasz how colorize some words ?
For example invoke draw yellow.

I try do colorize but get strange result.
Last char 'e' was yellow, but 'invok' another color.
When i press space and delete space all word 'invoke' was yellow and all next chars too(in this text line).

Code:

macro myColoriz4 chWord,ofst {local l1
      sub al,al
      cmp dword [esi+ofst],chWord
      jnz l1
      inc al
l1:
      }
macro myColoriz2 chWord,ofst {local l1
      sub al,al
      cmp word [esi+ofst],chWord
      jnz l1
      inc al
l1:
      }
macro  SetClrTxt chClr { local u1
       test al,al
       jz   u1
       movd eax,xmm1
       ;sub  dword [eax],
       add  dword [eax+8],24
       invoke  SetTextColor,ebx,chClr
u1:
       }
color_ok:       
        mov     ecx,[esp]
        mov     eax,[font_width]
        mul     ecx
        add     eax,[rect.left]
        mov     [rect.right],eax
        lea     eax,[rect]
        push eax ecx
        movd  xmm1,eax
        myColoriz4 'invo',0
        myColoriz2 'ke',4
        SetClrTxt  0xFFEE00
        pop ecx eax        
        invoke  DrawText,ebx,esi,ecx,eax,DT_LEFT+DT_NOPREFIX+DT_SINGLELINE

Do you ask how to do it with FEDIT control? Because there you would need to set up syntax highlighting routines, but the code snippets that you provided have nothing to do with FEDIT.

The implementation of WM_PAINT is such that it updates only the portions of the window that have been invalidated (with InvalidateRect), and it is done in the "refresh_line" loop, where the updated text is compared to the previous snapshot in order to detect which letters have changed and need to be redrawn.

Note that the content of the window, which is checked for changes, is kept in a format similar to DOS text mode (in fact, in case of fasm's IDE for DOS, which is also based on fedit, it translates directly to the text mode video memory), each character is two bytes, one for ASCII code and the next one for color (as assigned by the syntax highlighting procedure). If neither of them changes, the character does not become a part of invalidated (and therefore redrawn by WM_PAINT) region.

To alter the color of the text, you should use customized syntax highlighting procedure (set up with FEM_SETSYNTAXHIGHLIGHT message), not change WM_PAINT code.

Ok.
I found:

Code:

;FEDIT.inc this.
proc SyntaxProc lpLine,uChars,lpColors
        ret
endp

But how colorize word 'invoke' to yellow color ?
Because i don't want changed others colors. For example i don`t change color word 'mov' or word 'call'
And don`t change color for []\,.; and digits 'string ' and simple text.

I found this example. But not understooded how do colorize only for word 'invoke'

Code:

invoke  SendMessage,[hwnd],FEM_SETSYNTAXHIGHLIGHT,asm_syntax_colors,fasm_syntax

I do this. Perhaps maybe all looks fine for word 'invoke' Smile

Code:

cmp     dword [esi],'invo'
        jnz     .scan_syntax
        cmp     word [esi+4],'ke'
        jnz     .scan_syntax
        mov     al,5
        stosb
        stosb
        stosb
        stosb
        stosb
        stosb
        sub    ecx,7
        add    esi,7
        mov    al,20h
        sub    ah,ah
        jmp    .check_character

Yes ! I done.

Tomasz its right ?
I mean select all chars in current line:

Code:

xorps   xmm1,xmm1
movups dqword    [fepos],xmm1
mov     [fepos.selectionPosition],1        
invoke  SendMessage,[hwnd],FEM_GETLINELENGTH,[fepos.caretLine],0
inc     eax
mov     [fepos.caretPosition],eax
invoke  SendMessage,[hwnd],FEM_SETPOS,fepos,0
